Structure and cleavage of monosodium urate monohydrate crystals†
Abstract
The structural study of monosodium urate monohydrate, as the principal component in gout stones, reveals that a simple and biocompatible way to break down the crystals into polymerised molecules at pH 7.4 (the acidity of normal human blood) is to peel them off along the [001] direction by sonication.
